摘要
针对PEG共混膜的结构、膜中交联PEG的性质以及膜的热调节性能,分别采用扫描电镜(SEM)、红外光谱(IR)和差热分析法(DSC)等测试手段进行了分析,探讨了PEG共混对膜结构的影响以及交联PEG、PEG分子质量和PEG/PU共混比对热性能的影响.结果表明:PEG的加入赋予涂层膜耐久热活性,PEG共混使膜具有透湿性和热性能的协同作用.
The structure of the PEG admixed membrane, the properties of th e crosslinking PEG in the membrane and the thermal regulation performance of the membrane were considered, and the test means such as SEM, IR, DSC etc. were use d for the analysis to investigate the influence of PEG admixing on the membrane structure and the influence of crosslinking PEG, its mol. wt, and the PEG/PU adm ixing ratio on the thermal properties. The results showed that the addition of P EG gave durable thermal reactivity to the coating membrane, and that the PEG adm ixing formed a coordinating effect of the membrane to the wet penetration and th ermal properties.
